Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed November 19, 1912. Serial No. 732,283.

To all whom 2'2? may concern:

Be it lmown that I, JOSEPH Woons, a subject of the King of Great Britain, and resident of the town of Herbert, Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Plows, specification.

The invention relates to improvements in plows, as described in the present specification, and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel arrangement and construction of parts, whereby the plow-share is fitted with headed studs and adapted to slide into grooves carried by the frog, and held therein by a suitable worm screw.

The objects of the invention are to simplify the construction of plows, whereby the share may be quickly attached or detached in a simple manner and by an inex- I attached thereto.

pensive means. 7

In the drawings, Figure 1 is a perspective view of the mold-board with the share Fig. 2 is a perspective view from the under side of the mold-board with the share attached thereto. Fig. 3 is a perspective view from the under side, showing the mold-board with the share detached therefrom.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the moldboard attached to the land side 2 in the customary manner at the forward end thereof,

a and having the cross brace 3 extending thereacross adjacent the rear end thereof.

4 is the frog secured as customary on the inner sides of the mold-board on the land side, and forming a reinforcing angle brace.

5 are slots formed in the forward edge of the frog 4:, and extending angularly toward the cross-brace 3.

6 is a bracket piece secured to the moldboard 1 immediately back of the frog 4:, and having the slot 7 therein extending parallel with the slots 5.

8 is the share formed to fit against the forward edge of the mo1d=board 1, as 011s of which the following is a tomary in plow construction, and practically forming a continuation thereof.

9 are headed studs projecting from the inner side of the share 8, and spaced to agree with the slots 5 and 7 said slots preferably being tapered whereby the headed studs may slide thereinto, and gradually wedge as they approach the inner ends of the slots. One of the studs lettered 9 has the lateral and threaded orifice 10 extending therethrough.

11 is a bearing bracket secured to the cross-brace 3, and having the lateral orifice 12 therethrough.

13 is a worm screw having the threaded end 14 and the knurled head 15 forming a hand wheel. The worm screw 13 is inserted through the orifice 12 of the bracket 11, and the threaded end 14 thereof is screwed intothe correspondingly threaded orifice 10 of the stud 9 and draws upon the stud 9 to move the entire share into position against the mold-board with the several studs 9 at the inner end of the several slots 5 and 7.

It will be understood that the share can be readily detached from the mold-board by unscrewing the worm screw 13 to release the same.

The several studs securely held as they are in the several slots of the mold-board frog and bracket complete a strong and durable means for fastening the share to the plow with the advantage of being quickly detachable by the simple operation of turning the hand wheel of the worm screw entirely obviating the necessity of reaching under and about the interior of the plow to unfasten screws or bolts as has heretofore been necessary in the customary construction.

What I claim as myinvention is:

In a plow, the combination with the mold-board and land side having a bracepiece extending therebetween, of an angularly shaped frog secured between the inner sides of said mold-board and said land side and forming a reinforcing angle brace and having slots formed at intervals along the forward edge and extending parallel one to the other and toward said cross brace, a bracket-piece secured to said mold-board along said side frog and having a tapered slot in the end thereof paralleling the slots in said frog a plow-share formed to fit against the forward edge of said mold-board and having headed studs projecting therefrom and passing into the slots in said frog and said bracket and a Worm screw having a hand-grip formed at one end thereof inserted through a suitable orifice in said cross brace and having the threaded end thereof 10 fitting a correspondingly threaded orifice in the head of one of said headed studs Signed at Herbert, Saskatchewan, this 18th day of October 1912.
